Why you received this notice

We found your income tax needs to be adjusted because of information we received from others like your employer or bank. There were differences between what you reported on your tax form and what we received from them.

The notice isn’t a bill or audit. It notifies you of a proposed change in your tax. It explains how the amount was calculated, what to do if you agree or disagree and how you can challenge the decision in U.S. Tax Court if you choose.

What you need to do

Read the notice carefully. The amounts due on the enclosed Form 5564, Notice of Deficiency – Waiver, may not match your prior notice amount due. This is because you can't challenge all items in U.S. Tax Court.

Reply to the notice by the date listed.

If you agree with the proposed changes

Follow the notice instructions on how to respond. Reply to us with the enclosed Form 5564.

If you don’t agree

Reply to us right away. We’ll work with you to resolve your issue during the 90-day response period. You also have the right to file a petition with the U.S. Tax Court if you feel you need to.

Follow these steps:

If you have additional information or if what you reported is incorrect

Reply to us as soon as possible with the information you want us to consider. We can’t extend the time you have to file a petition with the U.S. Tax Court if you choose to do so.

Include a signed statement to support your position. You can also call us at the telephone number on your notice. We can generally accept information over the phone.

If you received income considered nontaxable under state relief, the Infrastructure Investment and Jobs Acts or a similar reason, include a signed statement with the response form.

If the information others reported to us isn’t correct

Contact the business or person who reported the information. Ask them for a corrected income document or a statement to support the reason it’s in error.

Reply to us to inform us as soon as possible if you’re waiting for their correction or statement. We’ll continue to work with you during the 90-day response period.

If you want to challenge the proposed change in Tax Court

Follow the notice instructions to file a petition with the U.S. Tax Court.

File your petition by the date listed on the notice. The Tax Court can’t consider your case if you file the petition late. We’ll work with you to resolve your issues during the 90-day period, but this won’t extend the time you have to file a petition in Tax Court.

Why did it take you so long to contact me about this matter?

Our systems match the information you report on your tax return with information reported by employers, banks, businesses, and others. This matching takes several months to complete.

Tips for next year

To file an accurate return:

  • Keep complete records.
  • Include all income on your tax return.

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.

Not advice. Not a filing. Verify with a licensed professional. Rules change by year and facts.
